Those are materials specifically intended to support particular lectures. Some of that material is misleading or incorrect when taken out of context of the specific graduate level EE classes and particular group of students being taught at the time. If it had been intended for a general audience, Wes would have made it available

While clicking through the pages of this presentation I came across the RLB-18 design and assume it's a return loss bridge. Is anyone aware of this design and any of the pertinent details?

Phil. You didn't take the hint, so I'll be blunt. That link was posted to this website without my permission. Let's not discuss those Portland State University course materials

i apologise for the link. it was entirely unintended.
i had just placed an order for the n2pk vna with makarov and then i
remembered that wes had disussed this vna somewhere.
so, i googled 'vna wes hayward'. the first link that it threw up was this
pdf, you might try this yourself.
i didn't realise that it was from your course material. i posted the link to
emrfd without even realizing where it was from. this is norm. All URLs are
public domain.

i can assure you that i had no intention of infringing upon the university
course materials.

as all urls are by nature public and they will be indexed as a matter of
course by search engines and thrown out to unsuspecting surfers like me.
there are two things you can do to avoid this problem.

1. create a robots.txt file on your website. this will advise the search
engines against indexing specific pages, images and pdfs on your website.
however, there is no guarantee that the spiders will actually respect it.

2. hide the content behind a form or a login. so that it is not available as
a static link.

sorry for leaking out the course material.

Ashhar is correct in that this is the top hit on Google for that search
string, or at least it is now. Whether it was intended for global
publication or not, it was published globally.

I am now rather curious about you statement "Some of that material is
misleading or incorrect", since as a description of an amateur RF lab it
all looked quite reasonable and consistent with other published material
at that level. Was that just a generic warning or is there something
wrong that I missed?

Maybe I don't understand stand something. Is there a ban on posting links
here without permission? Otherwise it is hard to understand why a link to a
public web page would be off limits.

I went up a level on the site to see what other things might be there. What
I found was something that I have found countless other times when I have
been Googling: an instructor's site that posted materials such as lecture
notes for various classes, as well as copies of papers that have been
published in journals. Many institutions (e.g., MIT) have made it a policy
to publish this type of material and more for public use.

I will note that the PDF in question has no restrictions or copyrights noted
on the title page or anywhere else I could see. So again, this seems like
material that was knowingly made public and has no restrictions on its use.

The PDF in question is also directly related to the subject of this group.

I've published a bunch of ham project descriptions, as well as notes and
PowerPoint presentations from a couple hamfest seminars on the web.

No one is allowed to look at them. ;^)

Certainly no offense meant on this end and it's obvious that this is a very touchy subject. I'll leave it alone and apologize for any offense taken.
